Haagen-Dazs and its seasonal products

Yummy! Haagen-Dazs, ice cream, is a worldwide product that everyone loves. I ate them often when I was in the US, which tasted slight differently from what we have in Japan (I believe due to the the difference in manufacturing company, and maybe for marketing reason?). I eat them occasionally here in Tokyo, too :) I especially love all the "seasonal products". "Lemon Ginger Float" for summer, "Pumpkin" and "Japanese Chestnut" for autumn and many more. 
Check out Haagen-Dazs website for details of its products in Japan (Japanese only, unfortunately)
